What looked like a routine missing person's case involving a young wife and mother should’ve been changed to a suspected abduction. But it’s too late. Twenty years ago, a young woman fell tragically to her death. The only people with her were four schoolfriends, one of whom (or maybe all) is responsible. Now there's someone intent on letting them have their just deserts. DCI Andrew Fenwick is soon caught in a desperate race against time to find the murderer before he completes his brutal vendetta.
